The Aztecs sacrificed about 250,000 people, or about 1% of their population, each year.
As of 2015, indigenous people make up 21.5% of Mexico’s population (25 million people).
8 out of the 52 U.S. states exist on the land that used to belong to Mexico.
Each year, residents of Naco, Mexico, join those of Naco, Arizona, for a volleyball match over the fence separating the two countries.

Changing the classification score cutoff drastically changes confusion matrices and model performance.
Ideal cutoff for current random forest model seems to be somewhere around 0.85.
Arguably better results with a simple neural network model (MLP with 5 hidden layers, no regularization).
